Discovered attacks

A piece slips off the line and an attack springs open behind it. The positions gathered here are the ones where the discovery wins most beautifully, ordered from the sharpest down.

Discovered attacks in Chess960

A discovered attack is the chessboard’s trap door. One piece moves, and in moving it uncovers a second piece — a bishop, rook or queen that was hidden behind it — whose line of fire now falls on an undefended target or the king. Two things happen in a single move, so the defender often sees only the piece that shifted and misses the one that spoke.

Chess960 makes the device especially venomous. With the back rank shuffled into one of 960 starting layouts, bishops and rooks command diagonals and files that no standard opening would produce, so the piece lurking behind the screen is rarely where intuition expects it. Discoveries here grow straight out of the unusual starting geometry rather than from memorised patterns.

This ranking gathers the positions where the discovery is most decisive and orders them from the sharpest down — the cleaner the concealment and the heavier the blow it unveils, the higher a position sits.
